Specification of Letters Patent.

Patented Nov. 28, 1911.

Serial No. 633,877.

the art to which it appertains to make and use the same.

This invention relates to a new and useful attachment for cultivators.

The object of the invention is to provide a novel attachment for cultivators, adapted for holding the shovels (not shown) of cultivators spaced apart, for plowing corn and cotton and similar products.

A further object of the invention is the provision of means for increasing or decreasing the space between the shovels, and holding them so adjusted.

In the drawings there is disclosed only one form of the present invention, but in practical fields this form may require alterations, to which the applicant is entitled, provided the alterations are comprehended within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings :Figure 1 is a View in perspective of the attachment, showing the same detached from the cultivator. Fig. 2 is a perspective view of a portion of the attachment. Fig. 3 is a sectional view on line 55 of Fig. 2.

Referring more especially to the drawings, 4 and 5 designate shovel beams adapted to be connected to acultivator (not shown). Connected to the beam 5 by means of the plate 6 and the nuts 7 is the staple 8. Connected to the staple 8 is the ring 9. Arching over the beam 4 is a staple-10, similar to the staple 8. The end portions of the staple 10 passes through the plates 11 and 12, which are secured to the end portions of the staple by means of the nuts 13. The plate 12 is rovided with an extension 14, which is twisted, as at 15, at right angles to the body of the plate 12. The extension 14 is provided with a plurality of apertures 16. Secured to the beam 4 by means of the staple 10 is a loop 17. Passing through the loop 17 is a rack bar 18, which terminates at one end into an arched extension 19, the end 20 of which connects to the ring 9. The loop 17 constitutes means for guiding the rack bar, as the shovels (not shown) of the beams 4 and 5 are moved apart or brought together. Connected to the extension 14 is the lower end of the lever 21, by means of the bolt and nut 22 and 23. This lever 21 may be adjusted with regard to the extension 14, by adjusting the bolt 22 in any one of the apertures '16.

Bolted to the lever by means of the bolts 24 is a plate 25 having an upper outwardly to hold the various parts of the attachment and the beams 4 and 5 in adjusted positions. To hold the bolt 28 in engagement with the teeth of the rack bar, the same is provided with a shoulder 29, between which and the lug 26, a spring 30 00- operates. Connected to the upper ends of the bolt 28, as shown at 31 is a rod 32, which in turn is connected, as at 33 to a hand grip 34. The hand grip 34 is pivoted at 35, adj acent the handle end of thelever 21. Connecting the lever 21 and the arched portion 19 of the rack bar are the link bars 36, one arranged upon each side of the arched portion of the rack bar.

As the lever 21 is swung or oscillated upon its fulcrum, that is, when the bolt 28 is withdrawn from the teeth of the rack bar, the rack bar is moved in one direction or the other, While the beam 4 is moved in the opposite direction, through its connection with the lower end of the lever 21, thus increasing or decreasing'the space between the shovels (not shown) of the beams 4 and 5. I/Vhen the hand grip 34.is released, after adjusting the parts of the attachment as desired, the bolt 28 will again engage the teeth of the rack bar.

From the foregoing it is to be observed that there has been produced a novel, simple and eflicient device for adjusting shovels toward and away from one another, and one which has been found'exceedingly practicable.

The invention having been set forth, what is claimed as new and useful is 1. In combination, a pair of shovel beams, a link connected to one of the beams, a guide loop connected with the beam having the link, an arched bar connected at one end to the other beam and provided with a laterally extending rack extension slidably passing through the guide loop, a lever pivoted to the link and provided wit-h a spring retained bolt to engage the teeth or the rack extension, and links pivoted between the arched bar and the lever, one upon each side.

a 2-. In combination, a pair of shovel beams, a link connected to one of the beams, a guide loop connected to the beam having 4 the link, an arched bar connected at one end to the other beam and provided with a laterally extending rack extension slidably passing through the guide loop, a lever adjustably pivoted to the link, a frame car ried by the lever and provided with an overhanging portion to hold the lever adjacent the laterally extending rack, a spring retained bolt mounted in the frame adapted ttiengage the teeth of the rack extension, and links pivoted between the arched bar and the lever' one upon each side.

- In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
